Parallel
Leviticus 13:52
Brenton's English Septuagint · Berean Standard Bible
He shall burn the garment, either the warp or woof in woollen garments or in flaxen, or in any utensil of skin, in which there may be the plague; because it is a confirmed leprosy; it shall be burnt with fire.
He is to burn the fabric, weave, or knit, whether the contaminated item is wool or linen or leather. Since the mildew is harmful, the article must be burned up.
